Surgical Apgar Score predicts 30-day morbidity in elderly patients who undergo non-laparoscopic gynecologic surgery: A retrospective analysis.

INTRODUCTION

The aim of this study was to determine whether a preoperative health status index and intraoperative data could predict perioperative morbidity and mortality in women over the age of 65 years undergoing surgery for gynecologic disorders.

METHODS

The medical records of 68 female patients who were ≥65 years of age and who underwent surgery under general anesthesia in our institute from January 2014 to December 2015 were retrospectively reviewed. Preoperative data were extracted from a database and included comorbidities, American Society of Anesthesiologists physiological status classification, the Charlson Comorbidity Index, the Subjective Global Assessment 2011 revision, the subjects' risk of falling, body mass index, and age. The intraoperative factors investigated included the type of surgery and the Surgical Apgar Score (SAS). Major postoperative complications were defined as > Grade 3 based on the Clavien-Dindo classification version 2.0.

RESULTS

Of the 68 elderly gynecological patients, 6 (8.8%) developed serious Grade 3 or worse complications within 30 days of surgery. The only factor that significantly affected postoperative complications was the SAS, an index of the patient's intraoperative condition. The optimum cut-off SAS for the occurrence of complications was determined by the receiver operating characteristic curve to be ≤ 6 points; a score ≤6 points predicted the development of postoperative complications with 66.7% sensitivity and 79.0% specificity.

CONCLUSION

In this study, the SAS predicted the development of serious complications in elderly gynecological patients within 30 days of surgery more accurately than did other comorbidities, preoperative assessments, and type of surgery.
